ERW Steel Pipe, Straight Seam Pipe, Youfa Thick Walled

The ERW steel pipe is also known as straight seam pipe. It is manufactured by using electric resistance welding. The weld lies inside the tube and is not visible from the outside. The tube is commonly used in low pressure fluid conveyance applications, such as the transfer of water, coal gas, air, oil, and steam.

Difference between ERW, DOM and Seamless Tube | Metal

ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round , square and rectangular steel tubing .

LSAW Steel Pipe, DSAW Steel Pipe, Straight Seam Welded

LSAW steel pipe, hot-rolled or cold-rolled steel sheet or steel coil made of steel pipe welding equipment in the straight seam welding are called the straight seam welded pipe. It is cut into strips by a steel strip, and then wrapped into a tubular cold mold. Then a special welder and then a seam welded. Outer weld brightly polished.

Straight seam steel pipe, tube blank deformation process

The deformation process of the straight seam steel pipe and the tube in the forming machine is very complicated. It includes the longitudinal deformation, the transverse deformation of the straight seam steel pipe and the deformation of the section.
